Joel describes the spiritual battle that will take place at the end of this age when the mighty army of saints will fight with Jesus in the last great battle. He desribes the day of the Lord and how great and terrible it will be. He asks the question, "Who can endure."
As you read this passage, know with an assurance that you will endure because I am the enduring One Who lives within you. The battle is Mine and the victory is yours. Joel gives the call for people in these end days to turn to Me with all of their hearts with fasting, with weeping, and with mourning. He exhorts them rend their hearts, and not their garments. Then he gives a beautiful description of Me and My character. Listen to His words:
Return to the LORD your God, for He is gracious and merciful, slow to anger, and of great kindness; and He relents from doing harm.
Pray for those in these last days who have not rendered their hearts to Me. Part of the word "surrender," is "render." You can surrender many things to Me, but I am after your heart to be totally surrendered to Me. When you surrender your heart to Me, I will give you the power to endure until the end.
